Loops make code.org

The most common usage of a for loop is simply to use it as a counting loop to execute a block of code a certain number of times. Here is a typical construct for loop used to count from 0 to 3 to execute the block of code 4 times: for (var i = 0; i < 4; i++) initialization var i = 0; is executed once, before anything else.

The conditional loops let you run some part of a program multiples times while some condtion remains true. In MakeCode these conditional loops are in the while, for, and repeat blocks: In JavaScript, the code inside the loops is surrounded by a loop statement, its condition, and some braces { }.

Let’s create a for loop where 0 is the loop’s starting value, i is the index variable, and 4 is the ending value. The index variable i starts at 0 and increases by 1 each time through the loop. The loop ends when i = 4. 3. Consider the following code for (let i1 = 0; i1 < 6; i1++) { basic.showNumber(i1, 150) }Like the previous unit, students learn the core concepts of lists, loops, and traversals through a series of EIPM lesson sequences.
